T4R V8 reliability

I'm the Parts Manager of a Toyota dealership. The 2UZ is legendary in its reliability. We see them come through here often with 500,000 + kms. Not that the 4.0L is poor (as it is also has exceptionally few issues) but I'd say I've definitely seen more 1GR's being pulled than 2UZ's due to motor issues.
 
Surprised no one has mentioned the million mile 4.7 V8 Tundra

Didn't they tear that truck down and determine that it still met new-vehicle tolerances in almost every section, engine included?

They did indeed tear down the truck, including the engine after running it on a dyno, the Techs rated the engine as 99/100, they were very surprised how little wear the engine had, and the dyno test rated it slightly better than some of their new engines, but they contributed that to it being "broke-in" compared to a new engine.

Here's a link to a article from "Truck Trend" on the tear down.

Million Mile Tundra: The Tear Down
 
203k on mine and only thing that has ever needed replacement was a coil pack.

Timing belt has 120k on it....should get around to changing that soon

My '07 has 87k on it and I'm planning on doing the belt soon. I hear 6 years or 90k whatever comes first. Well, it's been 12 years and almost 90k. I don't want to take my chances.
 
I have an '04 SR5 V8 that I bought a year ago from the original owner with 35K miles. The secondary pump affects only 2005+ vehicles. I had the timing belt and water pump replaced by Toyota, obviously not due to miles but age. The original parts removed looked new and I could not see signs of wear or aging. Granted it has low miles but has lasted trouble free for 15 years. The V8 is very quiet and smooth. The only thing you might have a problem with is Traction control and ABS light might come on. There is a reset procedure for that listed on this forum. I've only heard great things about Toyota vehicles and would not hesitate to buy another Toyota or Lexus.

Regarding how long the engine lasts trouble-free (see below), this will most likely be the last vehicle I would NEED to buy. It's got all the cargo and passenger space I need, towing capacity, longevity. I drive only 7K miles a year so I would probably have to put this 4Runner in my will, and I'm not that old yet. Seriously.

The 2UZ-FE Engine Problems and Reliability

Toyota 4.7L 2UZ-FE Engine Specs, Reliability, Oil | Tundra, LX 470 engine

The 2UZ-FE engines are almost bulletproof, the most reliable and durable engines from the Toyota corporation. These engines do not have any design flaws, meaning lash, noise, wheezing cannot be found. The engine has a timing belt that needs the replacement every 90,000 miles. The timing belt is costly but on the other hand is a lot of extra money to repair the considerable engine disaster because of the pistons will hit the valves if the timing belt breaks. Thankfully, the cast iron block is more durable and repairable more easily.

The engine longevity depends on how well and periodically was maintenance, the quality of oil and gas, driven style and conditions. But the non-problem average mileage for cars with the 2UZ-FE is about 300,000 miles.

What is up with all the newbs necro'ing 10+ year threads this week :noidea:

I know right? And many of them haven't even been bumped for good reason.

:bump2::bump2:

Newbs? You’re both “newbs”, relatively speaking.

I bet you’re also the deadbeats clowning new folks at the gym who are just trying to better themselves.

We all start somewhere.
 
Does anyone know if the 2UZ-FE in the 4Runner is built in the U.S. or Japan? I know the Land Cruiser's 2UZ is from Japan, but the Sequoia's 2UZ is built in the states.

The 4Runners are built/assembled in Japan so I'd imagine the engines are too.
 
I have a 07 limited with the 4.7 and have 254, 000 miles. Aside from timing belts and water pumps , have not changed any other hard parts.
 
Generally when a vehicle is overpowered, which one could argue that the V-8 T4R models are to a certain degree, the engine/power train will have increased longevity.

Compare the curb weights of a LC and Seq of which the same design is used versus a 4Runner.
